Suppose that two objects attract each other with a gravitational force of 3 N. If the mass of both objects remains unchanged, and the distance between masses was cut in half what would be the new force of attraction between the two objects? *

a. 6N
b. 0.25 N
c. 12 N
d. 0.5 N

a. 6N

Explanation:

Taking 9.81 as the acceleration due to gravity and the formula for calculation of a force, mass times acceleration:

To be clear, I'm using 9.81 for the sake of reducing variables and ease understanding of the formula. In a real life scenario, the acceleration could be any value, but in this specific scenario it can be disregarded.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
